The Oris AquisPro Date Calibre 400 is a serious Swiss-made professional diver’s watch with an impressive technical specification and a bold, purposeful presence.

At its heart is the Oris Calibre 400, Oris’ in-house automatic movement with a remarkable 120-hour power reserve**. This modern calibre is designed for everyday reliability, featuring automatic winding, stop-seconds, instantaneous date, fine timing adjustment and a strong focus on long-term performance.

The AquisPro is the professional-grade version of the famous Oris Aquis line. With its substantial 49.5 mm black DLC-coated titanium case, it has a powerful tool-watch character while remaining surprisingly wearable thanks to the lightweight titanium construction. The watch also features a ceramic minutes scale bezel, domed sapphire crystal with anti-reflective coating, and a robust black rubber strap with titanium folding clasp and extension.

This is a true professional diver’s watch, offering an exceptional 100 bar / 1,000 metres of water resistance. The black dial with wave structure gives the watch a technical and distinctive look, while the strong legibility and Super-LumiNova-filled hands and indices make it highly functional in demanding conditions.

One of the standout features of this AquisPro is Oris’ Rotation Safety System bezel. This professional diving bezel can be unlocked, adjusted and then securely locked into place, preventing accidental movement during use. Combined with its ceramic minutes scale and 1,000 metres of water resistance, it underlines the serious tool-watch character of this impressive professional diver.

This particular watch is a demo piece sourced from an official Oris retail shop and comes with Oris warranty. It is in near-new condition, showing only very light handling marks from fitting or trying on, which are hardly visible.

A spectacular professional dive watch with serious presence, impressive engineering and the excellent in-house Calibre 400 movement — built as a true instrument, but finished with the style and quality you expect from Oris.
